SAFETY-RAZOR.

Specification of Letters Patent.

Application filed September 9, 1919. Serial No. 322,678.

To all whom it may concern:

Be it known that I, CHRISTIAN E. A.

GRoNBnoH, a citizen of the United States,

residing at /Voodhaven, Queens county,

'Long Island, have invented certain new'and useful Improvements in Safet -Razors, of

which the following is a specification.

-My invention relates to an improved safety razor wherein different types of blades may be interchangeably used wlth equal facility.

rangement of the parts of the r'azor. I

other object is to provide in a razor of tlllS' The principal object of the invention is to provide a neat, simply constructed and compact safety razor designed to interehangeably receive different kinds of blades, without requiring any adjustment or rearkind, simple means for adjusting the depth or protrusion of the cutting edge of the blade so as to secure a more or less close shaving action, as may be desired.

The invention comprises the structural features 'and combinations hereinafter claimed, and fully described with reference to the accompanying drawingin which, I

Figure 1 is a perspective view of the 1mproved safety razor in condition for use; Fig. 2 is a similar view of the razor folded into inoperative condition; Fig. 3 is a simi-,

lar view of the razor with the parts in extended position, and showing also a blade and holder for receiving the latter; Figs. 4 and 5 are perspective views of two types of holders for receiving two different kinds ofblades. I

In carrying my inventlon into practice I preferably provide a separate holder for each different kind of blade to be used, and

construct the razor so that it may, with equal facility, receive any one holder at a time. without necessitating any adjustment, recon' struction or rearrangement of the parts of the razor.

Referring in detail to the accompanying drawing, 10 denotes a base plate having a clamping plate 11 hin ed to one end thereof, on the pintle 10 ounted for pivotal movement on the same. pintle is a handle section 12 which is approximately one-half as long as the clamping plate 11. At the end opposite the pintle 10 the clamping plate carries a hinged handle section 13 which is in all respects like the section 12. Each of the handle sections 12 and 13 is provided with an approximately central orifice 14:

,cated at 10 Patented May 3, 1921.

edge of the latter adjacent one side of the depression 15 is provided with a flat rib 16. One edge of the clamping plate 11 is pro-' v1 ded with afiange 17 designed to cooperate .wlth the rib 16 as hereinafter described.

.Formed in the non-depressed half of the base plate 10 is a slot 18 which is inclined with respect to. the longitudinal axis of the plate 10, and the edge of-plate l0 opposite the rib 16 may be provided with curvedguard teeth 19. p

The edge ofthe base plate 10 opposite that carrying the pintle 10 is undercut as indiso as to snugly receive therein. the hinge structure by means of which the handle section 13 is secured to the plate 11.

Each handle section is mounted on its pintle 'by means of a web.20 extending at right angles, or substantially so, to the plane of the handle section, so that when the handle sect1ons are moved lnto the'position shown in Fig. 1 the pressure exerted by the finger and 4 thumb of the user on the handle sections will tend to force these webs against the. under face of the base plate 10 and enhance the clamping effect of the platell on a blade su ported by the plate 10. 4

Iolders for three types of blades are shown in the drawing. The holder of Fig. 3 is designed to receive a blade with a thickcried or reinforced back; the holder of Fig. 4 is designed to receive a blade having lugs extending outwardly from its opposite upper corners, and the holder of Fig. 5 is designed to receive the ordinary flexible double-edged blade having two orifices therein. The holders of Figs. 3 and a are more particularly adapted for single-edged blades. Any of these holders may be adjustably positioned and secured in the razor shown in Figs. 1 to 3.

The holder of Fig. 3 comprises a body portion 21 having a socket 22 at one edge thereof. Struck out of the metal of the body portion 21 is a downwardly directed finger 23 which is inclined in relation to the longiplate 10. The form of holder just described is constructed to receive a razor blade 24 having a reinforced or thickened edge 25 which may be slid into and out of the socket 22. To use this form of blade and holder, the blade is inserted in the holder and the latter placed on the plate 10 with the socket 22 in the depression 15, the finger 23 extending through the slot 18, and the cutting edge of the blade resting over the guard teeth 19. By moving the holder 2l22 lengthwise of the plate 10 the cutting edge of the blade may be caused to protrude to agreater or less extent toward the outer edges of the guard teeth, by reason of the coaction between the finger 23 and the walls of slot 18, and when the'de'sired adjustment has been secured the clamping plate 11 is moved toward the base plate 10 and the handle sections 13 and 14 turned into the position of Fig. 1.' In this position of the parts the holder and blade are securely held in position, as will be obvious.

In Fig. 4 thebody portion of the holder is denoted 21 and is provided at one of its longeredges with an upstanding flange 22 and at each of its opposite shorter edges with an upstanding lug 22 The body portion has struck therefrom a downwardly turned inclined finger 23. This form of holder receives a blade having projecting edge lugs which are positioned between the ends of the flange 22 and the lugs 22 when the blade is placed on the body portion 21. The holder of Fig. at is placed on the base plate 10 with the finger 23 extending through the slot-18, and is held in position by the clamping plate 11.

The. holder of Fig. 5 comprises a body portion or plate 21 having oppositely disposed hollow studs 21 struck up therefrom, and a downwardly extending inclined finger 23". A double edged blade may be placed on this holder, with the two holes in the blade taking over the studs 21. lVhen the holder and blade are placed on the base plate 10 one edge of the blade (that not used for shaving) will lie on the flat rib 16 in position to be engaged and clamped by the flange 17 when the plate 11 is in clamping position.

It will be understood that adjustment of the cutting edge of the blades in the forms of Figs. at and 5 is obtained in the same manner as described with relation to the form of Fig. 3 and a repetition of this opedat the ends of said clamping plate, and

means whereby different kinds of blade holders may be received, mova'bly retained, and clamped, between saidv plates.

2 A safety razor comprising abase plate, a clamping plate movably connected therewith, handle members movably connected to each end of said clamping plate, and blade holding means adapted to be clamped to or released from thebase plate by greater or less pressure on said handle members.

3. A safety razor comprising a base plate and a clamping plate having one end pivotedto said base plate, handle members pivoted to the ends of said clamping plateand complemental means adjacent the rear edge of said plates adapted to limit the lateral movement of a blade holder confined therein.

4. A safety razor comprising a base plate, a clamping plate pivoted thereto, handle sections pivotally mounted at opposite ends of said clamping plate, and webs projecting from said handle sections and adapted, when the razor is closed, to press against the end and under face of said base plate and to lock said clamping plate in position.

5. The combination with the base plate of a safety razor, of a blade-holder adapted to be received by said base plate, an inclined slot formed in one of said members, and an inclined finger carried by the other member and designed to enter said slot.

(3. A safety razor comprising the combination with a base plate having a lengthwise depression and an inclined slot therein and a rib at one edge thereof, ofa clamping plate pivoted to said base plate and having a flange positioned to aline with and engage said rib, and a blade-holder adapted to be clamped between said plates, said bladeholder having a projecting inclined finger designed to extend through said slot.

In testimony whereof I have affixed my signature in presence of two witnesses.
